Will our information be given when we go to a website? As it seems that our location will be taken by them.

The least that can be known by a website is your IP (or typically your ISP box IP). You can't hide this unless you use a TRUSTED proxy or web proxy.

With your IP known, many "Whois" services offer exact map locationing of an IP. Well it's not always exact, but they can know your ISP and country/city.

Other info that can or can not be gathered depend on how hard/easy your security/privacy settings are configured in your browser and how much the browser is programmed to give. What, plugins and helper addins are installed on the browser and what Java/ActiveX components did you allow to run.
